I just made a portal demake after weeks and weeks of working on my itch.io posted it at like 1 in the morning today and now I see this. It kinda hurts.
However, your game featured a polished story, a good soundtrack and a large set of puzzles!
Mine is just a template.
All I'm doing here is an opening a portal to this kind of gameplay to people interested in doing so with GB Studio! edit: (credited your wonderful game as inspiration)
